I Can See Your Voice Season 2

I Can See Your Voice Season 2 VietSub is a popular international music game show based on the Korean version of the same name. The show introduces a group of "mysterious singers" and the task of the guest artists in each round is to eliminate the bad singers without hearing their real voices, with the help of advisors and clues provided by the show. The guest artists eliminate one or two mysterious singers at the end of each round, and the eliminated singers then perform their real voices on stage. At the end of the show, the chosen mysterious singer's true singing ability is revealed through a duet with one of the guest artists. The guest artist wins if they keep a good singer until the end of the show, and the remaining mysterious singer receives the show's prize.

In other versions, a non-celebrity player participates in the show. The player receives a cash prize for correctly eliminating each bad singer. In the final round, the player can choose to take the prize money if they think the last mysterious singer will sing badly, or continue the show for a chance to win a special prize.

The original version of the show has three rounds with different rules in each season. The first round is called "Singer's Visual," where the difference between good and bad singers is judged based on their appearance and costumes. The show provides a video of the player singing a song with the sound turned off, with only 0.3 seconds of sound to give a hint to the guest. A mysterious singer has two identities, and both identities will be revealed. The guest must determine who the good singer is based on their appearance.

The second round is called "Singer's Lip-sync," where the guest chooses based on the player's lip-sync performance. The good singer sings on a background track recorded by themselves, while the bad singer sings on a background track recorded by someone else to match their tone. The player and the lip-sync substitute appear together and both lip-sync to the same song, but only one of them is the owner of the pre-recorded track. The two voices are revealed simultaneously, and one of them belongs to the player. The guest must determine the player's real voice based on their lip-sync performance. The mysterious singers are divided into two groups, each performing a lip-sync performance based on the music of a song.

The third round is called "Singer's Proof," where each mysterious singer has evidence in various forms. The good singer has their own evidence, while the bad singer has fake evidence. Clues about the singing ability of each mysterious singer (such as photos, videos, certificates, etc.) are displayed on the screen. Any three chosen individuals (from the advisory board or the host) must use headphones to listen to the mysterious singer's voice for 30 seconds. After that, they have to defend the mysterious singer and convince the guest to choose them, regardless of whether they sing well or not. The host randomly assigns clues about the mysterious singer's identity. The guest must use the clue from the host to determine the identity of the mysterious singer, and then figure out who the bad singer is and who the good singer is.

There have been controversies surrounding the show. In August 2015, CJ ENM accused two Chinese shows, God of Songs and X-Singer, of plagiarizing the format and rules of I Can See Your Voice, making them unauthorized versions in China. However, God of Songs became successful with high viewership ratings and even created a trend on social media.

In an interview with CJ ENM, the owner of the format, Diane Min, in June 2020, the company revealed that they had a dispute with Is That Really Your Voice?, another game show format from Global Agency based in Turkey in 2013, which accused I Can See Your Voice of stealing their idea. However, the show was later adapted into Chinese and French versions.

I Can See Your Voice was nominated for Best Non-Scripted Entertainment at the 44th International Emmy Awards, along with Gogglebox, Adotada, and the eventual winner Allt för Sverige.

Thanks to the popularity of the show in Korea, I Can See Your Voice has become an international game show and is owned by CJ ENM and other TV production companies. Since 2016, the international versions of I Can See Your Voice have been broadcast in 18 countries worldwide. The Vietnamese version, Giọng ải giọng ai, has a similar format to I Can See Your Voice but is designed as a "duel format" and is recognized as part of the later international versions because its unique format has been used for production partners of I Can See Your Voice.)
